Diff Lockers...

[dysolve]

OK, I am getting sick and tired of people talking up welding there diffs and so on so heres a simple explaination for you all,

 

there are there MAJOR types of diff setup,

 

open

 

limited Slip (LSD)

 

Locked.

 

OPEN:

simply where its easier to turn the wheels the power will go.

E.G you are turning a corner and the outside wheel starts to spin, all of the

power will go to that wheel, so your car will slow down as you have NO

power to te ground.

 

LSD:

A limited slip diff will try to distro the power evenly between both wheels,

E.G you are turning a corner and the outside wheel starts to spin, The diff

will try to send more power to the inside wheel but no where near 100%, in

pratice its only about 30 to 40%, The reason its only 40% is because any

thing higher then this and the car gets hard to stearso your car will slow

down as you have little power to te ground. The major down fall to these

diff's is they only last for around 50000km, and then they just become an

open centre diff.

 

Locked:

OK there are hundreds of different ways to lock a diff all the way from weld

through to AIR. ALL a locked diff will do is make both wheels travel the

same distance and with the same power. Depending on you situation and

car type depends on which locker you would use. now everybody read the

next bit carefully as this will explain one thing......

E.G you are turning a corner both wheel will get the same power but the

both MUST also travel the same distance which means you will still lose

traction but the wheel to spin is more likely to be the inside wheel. You will

get what i call DIFF WINDUP which will make the wheel spin.

 

I will tell you a little story now. I drive an 1984 4WD hilux this is a part time 4WD so I run a Detriot locker in the front diff and an Airlocker in the rear, the reasons behind this are I CAN NOT turn with the rear diff locked let alone both so I can switch the rear diff from locked to unlocked with a switch on the dash and the front diff only locks when i have the front hubs locked, as my car runs a transfer case, once i lock my front hubs and change to 4WD my front and rear wheel MUST travel the same distance..

 

If any body has any further questions just ask...

 

do you want to know what this all explains??

 

well ANY car can drift, but ones that are high powered with a locked diff will always look the best,

 

I will be impressed when some body drifts an all wheel drive car with all THREE diffs locked.....

[demuire]

I think you got your inside and outside the wrong way around.

 

Probably should add that open diffs are kinda hard to drift. Much easier with a locker or LSD.

 

AWD drifting rocks.

Why are opens hard to drift? they are the easiest but it does not look like you are drifting because only one wheel spins....

my car was much more predictable with my locker than LSD

but you get pushed alot into corners, therefore you will understeer if you don't give it full throttle or use the handbrake

there is also more types of LSD's... clutch type, mechanical, etc, I don't remember 100%

but there was something like

if you have 1 rear wheel on dry tarmac, and the other is on ice

with a open diff, you will spin on the wheel that's on ice

with lsd #1 the lsd will put power to both wheels

with lsd #2 the lsd will put power to the wheel with best traction

correct me if i'm wrong...

 

I've just read it on the internett, so it must be true!

[demuire]

Why are opens hard to drift? they are the easiest but it does not look like you are drifting because only one wheel spins....

 

Because you can't use power to get or keep you sideways.

 

David: Yes I think you are right. LSD #1 is pretty much any of the basic sorts of LSD (clutch, etc), #2 is a Torsen.

[Mr Revhead[RL]]

iv seen plenty of 4wd cars do drifts on seal.

they are called WRC cars :)

[Ratty]

i have a video clip some where of an evo drifting i will dig it up tonight :)

 

hmmmm...... scandinavian

[Clown]

drifting with a open diff in a ute is a P.I.T.A, so unpredictable. gimmie LSD. The rolla will be running a welded diff till i get cash to get the LSD setup.

[Mr Revhead[RL]]

iv had a welded diff, in a mk1 escort with sidies etc

i will NEVER use a locked diff again

they suck. really suck if you need to use it on the road

[kangaroosa]

I used to have one in my road car too. I thought it was Great (not for doing wheelies, but the opposite). Sure it can be a but rough in carparks - but i only had 13" 175's with rock hard tyres on the rear and a stockish 4k.

It was more predictable than an open diff, so i always knew what it was going to do. So in some ways, it could be deemed to be Safer.

Except when at a red light and you have to move for an Ambulance. Then your RHS axel decides its going to break at that inappropriate time. :)

 

There are people for and people against. I guess it comes down to how tolerent you are.

[Ratty]

I had a banjo diff in my 2wd rodeo ute until it stoped turning the axels (donuts in the gravel ) :sad: $460 later i had a lsd centre out of a jackaroo 4wd or something, so they told me ( wreakers ) it fit straight in but when i put all the axel assembly back together there was some serious play with the wheels so i had to remove the right amount of shims to get it right. The wheel bearings were pressed on too :)

I had the bearings removed thanks to my mate at holden and new ones put on brakes ect anyway 1000 bucks later all up including the diff it has been the best money spent on that ute it is a bit wild in the wet sometimes but it feels much better than the old single spinner diff and it tends not to get boged on the building site as much ,as both wheels are turning in the sand not one like before lol if i had a beer for everytime i got boged i would be about half a carton better off

 

Now have driven both lsd and single spinners i find the lsd more enjoyable and a much better feel, as for a locked diff i would no. But i have heared the tyres screech on a vl at the petrol station ,i wouldnt like that attention.

[dysolve]

with diff lock's i can nearly drive up walls but my truck tried to fall back over its self next time we go away on a trip i will take movies of the differance between open and locked diffs

[Rolla__Boy]

How does a locker suck to use on the road??? They are great fun...and as everyone has said they are predictable...the only thing that sucked was wearing out tyres like they were free haha

[Mr Revhead[RL]]

they suck

 

at slow speed the understeer, the rough ride etc etc. just crap. ill never have one again

id rather have open.

 

they are ok in a competition car. but have no palce on the road. and no way are they safer.....

[Super Jamie]

they are ok in a competition car. but have no place on the road. and no way are they safer...

i would agree with this. breaking axles and voiding your compulsory third party insurance by driving a massively defective car is not a risk worth taking on the street

 

i'm not going to both with lsd for my hillclimb ke20
